Description

TECHNICAL FIELD

[0001] The utility model belongs to timber leftover material processing technical field, especially, relate to a kind of timber leftover material screening device. BACKGROUND

[0002] When wood is processed, a large amount of cutting leftover material will be generated when the board is cut to the appropriate size. Because the size of the wood raw material is different, the size of the leftover material generated when the wood is processed to the specified size will also be inconsistent. These leftover materials are usually in the form of thin strips and vary in thickness. When the leftover material for wood processing is recycled, a leftover material screening device for wood processing is needed.

[0003] When the leftover material for wood processing is screened, it is usually directly fed into the surface of the vibrating screen through the feeding hopper. During this process, the leftover material will first accumulate on the surface of the vibrating screen, so that the leftover material at the top will not be in contact with the vibrating screen until later, resulting in slightly poor screening efficiency and affecting the screening accuracy. Therefore, a leftover material screening device for wood is needed, which can uniformly distribute the leftover material entering the vibrating screen, so that the leftover material can swing down and be evenly distributed on the surface of the vibrating screen, thereby improving the efficiency of leftover material screening.
